AUTOMATIC STOP FOR WlRE BARBlNG MACHINES.

SPECIFICATION forming part oi Letters Patent No. 395,712, dated January 8, 1889.

I Application filed June 6, 1888. Serial No. 276,081. (No model.)

To (ZZZ whom it may concerw Be it known that I, ANDREW M. MUNsoN, a citizen of the United States, residing at Lee, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in Automatic Stops for \Vire-Barbing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying (.lrawings, and to letters or figures of reference marked thereon, which form a part of? this spectlication.

My invention has reference to certain improvements in machines for placing barbs upon t'enee-wire; and it consists, essentially, in devices for automatically stopping such machines in case of any accident to the wire as the latter is being fed to the machine, and in means for stopping the machine when the wire on the feed-reels becomes exhausted. Barb fence-wire now exclusively manufac tured by machines in which one or more fencewires are fed to the machine from rotating reels, and the wire from which the barbs are cut is fed to the machine at right angles to the feed of the main wire or wires. The expense of manufaeturing is largely determined by the number of machines which one man can operate. Both the main wires and barbing-wires are drawn through a guiding-sleeve or hollow cylinder by the feed-rollers, such guiding-sleeve being necessary to deliver the wire at the proper locality upon the rollers and to cause said wire to cross said rollers in a direct line. It frequently occurs that there are knots or splices in the wire, which catch at the entrance or within said sleeve, and thereby prevent the further progression of such lodged wire. As the wires are fed with considerable rapidity, the stoppage of one wire will cause a breakage between it and the twister, in which event the other wires will be fed into and clog the machine; but what-ever the precise result, it is obvious that the stoppage of any one of the three wires will work confusion and disaster within the machine, Again, frequently the wire in the process of being withdrawn from the reels upon which it is preliminarily coiled will become tangled, so as to prevent the further uncoiling of such wire from said reels and suspend the progress of such wire, with the same result as though said wire had caught on the sleeve, as aforesaid. Again, there are no less than three reels 10 be constantly watched by the operator, that the wire on them or some of them does not become entirely used up or tangled. These things re quire a constant watchfulness on. the part of the operator and, requiring him to constantly keep his eyes on the machine, limit the number of machines which he can super-intend. My invention has reference to the provision of certain devices by which any of these accidents to or interruptions of the feed of any of the wires, as well as the exhaustion of the latter at the teed-reels, can be utilized to automatically stop the machine without thedirect interference of the operator. It is obvious that this is -a great advantage and will increase the number of machines which any one operator can superintend, because if the machine can be made self-stopping in case the wire on the reels shall become exhausted, or in case of any interruption or suspension of the feed of said wires, the said machine will not require such close and continuous watchfulness on the part of the operator .as though he were required to personally stop the machine immediately upon the occurrence of any of these interruptions.

As my invention is intended, with, perhaps, slight and self-suggesting variations, to be applied to any of the various forms of barbmachines, and has reference solely to causing the lodging or catching of the wire to automatically suspend the operation of the machine, I do not deem it necessary to show or describe the particular operation of the barbing-machine any further than will render intelligible the mode of attachment thereto and operation of my invention.

In the drawings, Figure 1 is a side elevation of a portion of the frame of an ordinary barbmachine with my invention attached thereto. Fig.2 is an end view of the same. Fig. 3 is a detail of the reels from which the wire is un coiled in the process of barbing and the peculiar mode in which said reels are seated.

showing a spiral spring instead of rope for the connection. Fig. 8 is a detail in top plan of the standard and reel.

The standards 1, upon which the wires are pivoted, are placed slightly out of the perpendicular, with their upper ends slanted from the machine, in order that the reels 2, which are pivoted on the outer ends of the pivoted horizontal arms 3, may, from the weight of the wire thereon, swing backward away from the machine and have their normal position at the side of said standard 1. Each arm 3 consists simply of a round bar having a horizontal central portion, its outer end bent upward to form the pivotal seat for one of the reels 2, and its inner end bent down-' ward and inserted loosely in the socket 4c in the top of the standard 1. The top of the standard 1 is projected outwardly to form a support for the arm 3, and at its extremity provided with stop 5, which prevents the arm 3 from swinging away from the machine sufficiently far to be in a direct line with the discharge of the wire. Any stoppage or tangling of the wire therefore on the reels 2 will tend to cause said reels to be thrown toward the machine, the arm 3 swinging around toward the machine for that purpose. A short arm, (3, is also pivoted at its inner end in'the socket a, the inner end of the arm 3 passing down through said arm (5. The pivot for the arm 6 is formed simply by a downward projection on the lower surface of the inner end thereof, which enters the socket 4 around the inserted end of the arm 3. A vertical lug, '7, is formed on the inner end of the arm (5 in position to be engaged by the adjacent portion of the arm 3 as the latter swings inward, as aforesaid, in case of the tangling of the wire on the reel 2, and the free end of the arm 6 being projected from the standard 1 in the direction opposite to that of the arm 3 tends to throw the outer or free end of the arm 9 from the machine.

Two reels are placed on one standard at different altitudes, and one at the top of the other. A chain, 8, connects the outer end of arm (3 with the downward-projected arm 9, seated upon the horizontal rock-shaft10,suitably journaled to the end of the frame 11 of the main machine. Thus any tangle or stoppage in the uncoiling of the plain wire from the reel. 2 will result in drawing toward the machine the reels 2 and moving in a substantially horizontal plane the arm 3, and thereby moving from the machine the outer arm, 6, and through the medium of the chain 8 and arm 9 rocking the lower portion of the shaft 10 of the machine.

The transmission of this rocking movement to the devices for stopping the machine will be hereinafter described. The last end of the wire can be knotted or fastened to the reel so as to draw when the wire is exhausted.

12 is a lever seated vertically on the rockshaft 10 about centrally and in the line in which the wire passes from the reel 2 to the barbing mechanism. The lever 12 is provided near its upper end with the vertical slot 13, of such width as to permit the plain wires 14 to easily pass through said lever in their movement toward the barbing mechanism; but the slot 13 is not wide enough to permit the passage of a splice-knot or other enlargement on the wires 14. Therefore such enlargement or knot, which would otherwise catch at the sleeve aforesaid, (which is between the lever 12 and barbing mechanism,) is not permitted to proceed farther than the lever 12, and the catching of the latter has the effect to draw said lever toward the machine, and thereby rock inwardly the shaft 10, as before described in reference to a tangle on the reels. A coiled spring, 15, is placed on the shaft 10, near one end therof, and has one of its ends inserted in a box, 16, journal-bearings of shaft 10, and has its other end inserted in a collar, 17, on said shaft, and serves to throw the lever 12 back into position after the pressure of the obstruction on the wire has been removed. The collar 1.7 is seated by means of an ordinary set-screw, and thereby the tension of the spring 15 can be regulated as desired by twisting said collar 17 on the shaft. A short chain, 18, can be used to connect the lever 12 midway to the frame 11 and prevent said lever from being thrown too far back by the spring 15. The slot 13 is. used rather than a hole, so as to permit the oscillation of the lever 12 without forcing the wires 14c up or down. The walls of the slot 1.3 can be made of removable steel rods adjustable to and from each other.

A shaft, 19, corresponding in function to the shaft 10, is journaled horizontally to the side of the frame 11, near the reel 2, at the right hand, which contains the wire to be cut into barbs, and is located a short distance from the side of the machine, and operates substantially as has been described in reference to the m ain-wire reels 2, and is also adapted to actuate the arm (5, as has been before described, which latter is connected by chain 8 to the second arm 9, seated on shaft 19; and on shaft 19 is also seated a second lever, 29, provided with vertical slot. 13 for the passage through lever 20 of the wire 11 for barbing, an d the functions of the shaft 1.9, lever 20, and slot 13 therein are substantially the same as those mentioned in reference to the like end mechanism. The shaft 19 is provided at its end contiguous to the end of the shaft 10 with the bevel-pinion 21, and the shaftlO at it s end adjacent to the end of the shaft 19 is provided, with a like bevel-pinion, The oscillation, therefore, of the shaft 10 is communicated through the pinions 21 and 22 to the shaft 1.9, so that the lever 20 is oscillated, whether the obstruction of the wire takes place on either lever 12 or 20, and when the stoppage of the uncoiling of the wire occurs on any of the reels 2, or any obstruction occurs of the character named, each has the effect to rock the lever 20 toward the machine. The inward which forms one of the ing process has been suspended it is necessary to coii'icidently stop both the barbing mechanism and the twisters.

Referring to Fig. 4, 23 is the main drivingshaft of the barbing-machine, upon which is seated belt-pulley 24, which latter carries and is driven by the ordinary belt from the shopshaft. The pulley 2+ is held from lateral movement on the shaft 23 by means of collars 25, attached 011 said shaft at each side of said pulley by means of ordinary set-screws. A longitudinal slot, 26, is formed on the upper side of the shaft 23, extending a short distance within the inner collar, 25, and in said slot is seated the usual key, 27, pivoted at one end, and thereby adapted to be embedded in said slot or to be thrown out into engagement with a corresponding recess formed on the inner surface of the hub of the drive-pullcy 2t. (Not shown.)

A spring (not shown) is interposed bet ween the back of the key and bottom of the recess 26, which holds said key outward and in engagement with the recess aforesaid in the inner wall of the hub of the drive-wheel 2t.

The parts just described for attaching and detaching the pulley 2i to its shaft are old and well known, and I do not deem it necessary to make special description thereof. My invention in this department has more special reference to the mode of forcing said key 27 down into its bed and releasing pulley Si by means of intermediate mechanism communicating the oscillation of shaft 19 to a shifting collar 28, seated loosely on shaft 2 3. The inner end of the key 27 is projected slightly within the collar 25, and is provided with a lateral head, 2.), extending outward from the shaft and beveled downward and inward, as shown in Fig. el. The collar 28 has formed on its face adjacent to key 27 an annular opening, 30, flaring outward, (see end view thereof in Fig. 5,) which opening, when the collar 28 is slipped outward on shaft 23, as hereinafter described, passes over the head 29 of key 27 and forces the latter back into recess 26, and thereby releases the drive-pulley 24. and permits the latter to turn upon the shaft 23 without communicating rotation to the latter.

In the opening 30 is formed a stop, 31,which engages the head of the key 27 as the latter, by the momentum of the shaft 23, is carried around the opening 30, and in such engagement such momentum imparts a degree of rotation to collar 28 sutiicient to wind thereon an attached rope or chain, 32, the upper end of which is passed overap'ulley and attached in any suitable way to the ordinary shiftinglever for shifting the belt on the countershaft aforesaid, which drives the twisters, from the fixed pulley on said shaft to an idler thereon. The lower end of the rope or chain 32 is attached to the periphery of the collar 28 in the external annular groove, 33, therein, and inasmuch as the required momentum of the shaft 23 may vary at different times it would be well to have a portion at least of the rope or chain 532 consist of a spiral spring, that unusual winding of the lower end of said rope might not break the latter or any of the upper parts to which it is attached. As the mode of attaching the upper end of the rope or chain to the ordinary shiftii'ig-lever and the operation of the latter are well known, I do not deem it necessary to show or describe the same.

The collar 28 is provided with a second annular groove, 34, parallel with and inside of groove 33. A vertical lever, 35, pivoted about centrally to the frame 11, and is provided at its upper end with a clutch to enter and loosely travers the groove 3+. The lower end of the lever 35 is connected by means of pitman 36 to an arm, 37, rigidly formed on shaft 19, said pitman 36 being pivotally con- 'neeted at one end to lever 35 and pivotally connected at its other end to arm 37.

It is obvious that the inward rocking of the upper side of shaft 1.), either through the lever 20 seated thereon or from the lever 12 seated on shaft 10, through the medium of beveled pinions 2] and 252, will have the effect of forcing the lower end of lever 35 inward and the upper end of said lever outward, thereby carrying collar 28 outward and over keyBT, as aforesaid. The unlocking of pulley 24-, as aforesaid, and shit ting of the belt which drives the twisters by means of the rope or chain 32, are substantially coincident movements, and thereby motion of both the barbing and twisting mechanism is at once suspended. After the occasion of the stopping of the machine has been removed the collar 28 may be slipped imvard, disengaging the key 27 by an outward pull by the operator of either lever 12 or 20.

As numerous machines of varied constructions are used for seating barb-wire, it is impracticable in one specification to illustrate or describe the various modes by which the rocking of the lever 12 or 20 can be applied to suspend the operation of the machine.

The upper ends of the levers 12 and 20 are provided with handles 38, by which said levers can be positively moved inward and stop the machine, orcan be returned to their vertical position.

While in the present instance feed-rolls to draw the wires forward from the reels are indicated at fl] and at, Fig. 6, I do not intend to confine myself to any special form of con structing or of operating these.
